these films are both hugely symbolic;They both require some good thinking afterward. They share an "epicness" (in their scale) about them that I don't want to spoil. I think they are nicely animated, and the color pallets are also oddly alike.

Both films have many subversive and psychological elements to the presentation. There's also an underlying religious theme within both.
Angel's Egg has more of a gothic style to it, however... while End of Eva has more of a traditional 90's art style.
